Abstract: The absolute configurations of three new enantiomerically pure ferrocenylphosphole compounds, namely (2S,4S,S_Fc)-4-methoxymethyl-2-[2-(9-thioxo-9 [lambda] ⁵-phosphafluoren-9-yl)ferrocenyl]-1,3-dioxane, [Fe(C₅H₅)(C₂₃H₂₂O₃PS)], (III), (S_Fc)-[2-(9-thioxo-9⁵-phosphafluoren-9-yl)ferrocenyl]methanol, [Fe(C₅H₅)(C₁₈H₁₄OPS)], (V), and (S_Fc)-diphenyl[2-(9-thioxo-9⁵-phosphafluoren-9-yl]ferrocenylmethyl]phosphine, [Fe(C₅H₅)(C₃₀H₂₃P₂)], (VIII), have been unambiguously established. All three ligands contain a planar chiral ferrocene group, bearing a dibenzophosphole and either a dioxane, a methanol or a diphenylphosphinomethane group on the same cyclopentadienyl. In compound (V), the occurrence of O-HS and C-HS hydrogen bonds results in the formation of a two-dimensional network parallel to (001). The geometry of the ferrocene frameworks agrees with related reported structures.

Formula: [Fe(C₅H₅)(C₂₃H₂₂O₃PS)], [Fe(C₅H₅)(C₁₈H₁₄OPS)] and [Fe(C₅H₅)(C₃₀H₂₃P₂)]
